How to play

Everything you need to master the game: rules, scoring, modes, tips and answers to common questions.

How it works

Three steps and you are playing

1
👀

Look at the grid

A grid full of identical images appears. One of them is different.

2

Tap the odd one

Find it before the timer runs out. The faster you click, the more points.

3

Earn stars

Every level gives you up to 3 stars. Stars unlock harder levels.

Scoring

How points work

⏱️

Speed bonus

The faster you find the odd image, the more points you earn. Replying immediately can almost double the base points.

🎯

Accuracy matters

Wrong taps end the round with no points. There is no penalty beyond losing that round, but you cannot guess.

1 to 3 stars per level

At the end of every level you get up to 3 stars based on your total score. Stars unlock new levels.

Star thresholds

☆☆
≥ 40%
You unlock the next level
★★
≥ 65%
Solid performance
★★★
≥ 90%
Master level — all 3 stars
Modes explained

Solo vs multiplayer

🎯

Solo · Levels

Progress through 30 levels at your own pace. Each level adds more cells, less time, or more rounds. Your stars and best scores are saved on your device — no account needed.

👥

Create a room

Create a room and share the 4-letter code with friends. Up to 20 players see the same grid and race for the fastest time. The game ends with a podium showing winners and tied players.

Pro tips

Tips to play better

  • 🔍
    Look at the whole grid

    Do not try to inspect cell by cell. Let your eyes catch the one that "feels different" with peripheral vision.

  • First instinct is usually right

    If you think you spotted it, tap. Hesitating costs you the speed bonus. Trust your visual system.

  • 🧘
    Stay relaxed

    Tension makes you tunnel-vision on small areas. Breathing and a relaxed gaze find odd patterns faster.

  • 🔄
    Replay levels for stars

    Did you only get 1 or 2 stars? Replay! Best score is kept, so you have nothing to lose and everything to gain.
